Poldilukud

Poldilukud refers to a specific type of lock mechanism commonly found in older buildings, particularly in Estonia and neighboring regions. These locks are characterized by their distinctive internal workings and often a unique key design. The term "poldilukud" itself is derived from Estonian words related to "bolt" or "latch" and "lock."

The construction of poldilukud typically involves a heavy-duty bolt or latch that engages deeply into the door frame. This robust design was intended to provide enhanced security, making them more difficult to force open compared to simpler locking mechanisms of their era. The keys for these locks were often elaborate, featuring intricate cuts and patterns that corresponded to the tumblers within the lock cylinder.

Historically, poldilukud were widely used for both residential and commercial properties due to their perceived strength and reliability. Their presence can often indicate the age and architectural style of a building. While modern security systems have largely replaced them in new constructions, poldilukud can still be found on many historic doors, contributing to their authentic character. Restoration efforts sometimes focus on preserving or repairing these original locking systems. The mechanisms are known for their durability, and many functioning examples still exist.
